I know, I know I'll probably get a few "Why the HECK..." and "Just eliminate the BCS..." comments, but PLEASE humor me on this one. I'm getting a Galant in ~1 month and am looking to keep it as stock appearing as possible. This includes keeping the stock airbox, BCS, vacuum lines, etc. So, when I put on the Hallman sitting on my desk should I hook it up BEFORE or AFTER the hose going to the BCS.

On the top (Before) image, I'm wondering whether to put the boost controller in the "B" line or in the "W" line.
Currently I'm thinking the "W" line after the BCS, but my thoughts have been known to change on a whim;) Again, if you're just going to tell me to eliminate the BCS or tap off of the BOV line don't bother posting. I found that tapping off of the BOV line for the boost controller resulted in varying boost levels and inaccurate BOV operation due to the two items "fighting" for boost/vacuum (although, this was with an electronic unit). The BCS stays for both stock appearance and semi-safety. Any help would be great y'all...

I put my MBC after the BCS when originally installed with no problems. Later I just tapped into the BOV line and ran it that way.

Yeah, that's what I was originally thinking. I'll be using a TMO stage III ECU also so the BCS won't limit boost, just bleed some off when there's excessive knock. Thanks for the input.
